My question to the experts here is, if a manned mission to Mars were to become a reality, how much water would be needed to pass a theoretical benchmark, for 15 years of travel ? ( assuming 15 years worth, is a safety net ).
This kind of food would need masses of water, would it not, added to the daily requirements of other water usages?
Is such travel possible today, based upon any assumptions made for the amount of water needed to be carried? I have no idea, but it seems a little far fetched?? (of course, number of crew needs to be considered, but I doubt a manned mission to Mars would not comprise less than 5 persons?
Genuine question guys....
